Yellowing new growth only


Happy frog on top ocean forest bottom 1/3 of 5 gallon fabric pot. AC Infinity ION 4 set at 5 18 inches above plants PPFD 450. I’ve been watering with only cal mag and silicon blast and PH 6.2. I flushed it yesterday and runoff was PPM 800 PH was 5.9. After flush Val mag and silicon blast only. Temps 74-76 RH low 60’s. Pink runtz auto just started showing week 4. Need some help guys. Thanks

It’s normal. Chlorophyll has not yet developed in the new growth. It will fill in with a darker shade of green over the next few days.

If it persists, then it is an iron deficiency. Are you feeding a complete nutrient product that also includes micronutrients (iron, copper, boron, manganese,…)

Agreed !! Came to say something similar

I have not fed yet letting it feed in the fox farms soil. I will be feeding maxi grow then maxi bloom but have not yet.

iirc Floramicro is the GH product that delivers micronutrients. Check the labels on Grow and Bloom. They may already have the micros in them.

FF soils contain sufficient nutes for 4 to 6 weeks from your last transplant.

The proper pH range for soil is 6.3 to 6.8. An out of range pH will cause problems with nutrient uptake.

Before I forget again: welcome to the forum.

Yes it is. For liquid 3 part.

These have everything in them in dry form as a 2 part feed mix.

Just sharin a lil info is all. :wink: :green_heart:

Thanks….i just fed maxi grow half dose

Just be careful with the pre amended soil and fert additions.
Usually not till the runoff reaches under the 1000 ppm’s mark is when most will start to supplement the fox farms.

Thanks….yesterday the runoff was 800 PPM today I fed 600 PPM of maxi grow and PH at 6.4.

Every time I see this bad short horrible type of growth I think lights too close.

Hard to achieve this without light stress

18 inches away with a PPFD at 450.

The other suggestions would be to stop using silica, don’t pH anything and don’t read soil runoff.

Soil buffers ph so do ferts no need to change, in fact the soils buffer is so large made up of tiny particles that breakdown into millions of ppm. That’s all your seeing in the runoff not your actual water and fert ppm so irrelevant to read or try check. Just flushing soil from the pot and reading that small amount which has no meaning.

Silica should be available in the soil anyway and it’s use for healthy plants negligible in effect plus it’s an un needed mineral to growth.

Sure your soil isn’t bad from all the amendments it didn’t need and probably need a good fertilising at this point if given nothing. I use a good soil it needs fertilizer before this point, a lighter soil needs it pretty much from the off.

Not bashing you bro but I have to disagree with pretty much everything you just said. Maybe it came off wrong but here goes.

This is the opposite of what most of us do. I pH everything going in and check my runoff to determine what is going on if I see something that doesn’t look quite right. Knowing your pH in/out and what your TDS is tells us if she is eating and if not, why not.

Again, this is how so many of us determine if she is hungry.

Not sure what you are saying 100% but silica is needed. For many reasons. Stronger healthier plants, aids in pest control, in flower aids in trichome production. I use Mammoth P in concentrate and AN Rhino Skin when transplanting.

A Lil passive aggressive nub to the OP. Nice.

Bonjoyle I agree and do/use everything you mentioned I just didn’t want to respond to the negative or incorrect people….thanks so much for your input. Imagine not PHing or reading g runoff….lmao. Have a great grow.

Sometimes in a virtual setting, it is hard. We don’t have voice tone, facial cues etc… and if your goal is always helping someone, then you just have to dive in once and awhile.

I do not know it all. Hell I don’t know alot, just ask the wife…but what I do know I know you know? I also understand that some people cannot even afford a pH pen or TDS meter and grow like mother nature intended. But we now know stuff we did not when I was young. A TDS pen, a pH what? These things were not things when I was a young grower. I like to keep it as simple as possible.

I use good genetics, good lighting, good soil and I have a few bells and whistles that aid in getting the best product I can for what I am doing.

Look what I can do…Haha!!!

Just take that one fact - you pH everything going in and read run off readings.

Soil is a far greater buffer than your oh efforts, so what were you hoping to achieve with a few hundred poms if oh liquid against a potential of millions of ppm buffer in the soil?

It’s just simple when you grow and pretend it’s not cannabis, you make it like soils don’t adjust pH and without amending they aren’t right for growing… so all the growers who don’t pH they are doing this growing how?

Not here to argue, if you know you know if you don’t you should learn what a soul is and it’s real buffering capability.

Runoff will just be made largely if this buffer, it doesn’t represent the soil or ppm you just washed a little away and read that giving no bearing on the real situation.

Or too bright which is definitely the problem here.

Never used silica a day in my life

I have to ask. How did people grow weed before the invention of ph and ppm pens?

Op turn the light intensity down or raise the light. You’re suffering light stress. Notice the leaf edges pointing up that’s a dead giveaway.
