im well in flower with 2 of my 3 plants (do si dos, lsd, critical all auto’s) they are in soil(biobizz allmix) lsd and do si dos sprouted the 27 of march, temps are between 21c to 27c, humidity now is at 45 to 55%(had problems before it wouldn’t go under 60%) ph is between 6/7 more towards 7(using ph papers) runoff is near 6, using biobizz trypack(1ml of biogrow, 3 of biobloom and 1 of topmax diluted in 1.5l, suggested in 1l but I’m scared of overfeeding) watering 2 times a week approximately one time only water and then with nutes, light is a viparspectra p1000(terrible choice my bad) 100w 300true watts, burned tips, on some leaves even the edges, general light color of the plant(greenish yellowish) small buds on the do si dos, lsd is doing better, critical is in early flower, rust spots an leaves, more to the bottom but also on top, some leaves are yellowing/browning from left to right an falling off, I tried different forums but no sure answer, please I’m desperate
Help is on the way. You’re in the right place ! @MidwestGuy @dbrn32 @beachglass
thx guys, im trying so hard that i cant even sleep at night ahahaha, i can’t see my plant looking so sad, expecially now, defs or problems in general can only mean extremely low yelds and bad buds sooo i give mi love and hopes to yall ahahaha
Hey welcome!! You really need to get a digital ph and tds meter. Looks like a cal-mag deficiency to me. Are you giving cal mag?
I started in soil but switched to coco. It’s made it more simplistic for me. Full strength nutes every watering from seedling to harvest.
Looks like a potassium deficiency. Maybe @Graysin can give you a definitive on that.
Seems right on point. @PurpNGold74 once told me potassium deficiency looks like the spotting on a banana.
@Breezy How long ago did you transplant? When did these issues develop? When you went from soil to coco did you change your feeding chart to reflect a different medium?
I guess I need to be more specific haha my bad. I meant after my run was finished with soil. My next run I went coco and never went back.
@paranoidperson , welcome. You’ll get help here for sure. Nothing wrong with pH strips, they don’t need batteries and calibration. I’d prune all the yellow and brown leaves. They won’t come back and they just deplete the plant when it needs extra P and K. Water them when the soil feels dry to the touch. Most likely a bit more than 2-3x a week as they get bigger. Perhaps every other day. Feed bloom nutrients with plenty of potassium and phosphorus at @ 1/2 strength. Keep temps @75F, RH@45-50%. And don’t harvest early or the weed will make you even more paranoid.
@Graysin and @The_Chef are spot on here. Im seeing a very hungry plant. Soil pH is uber important and those numbers seem very general. How are you taking pH measurements?
Id lean towards more of a lockout as u can see nitrogen (just straight yellow) phosphorus (the ‘burnt tips’ in overdrive) and potassium (yellowing with the spots). Thats alot going on. Either you need to bump up the total feed (bloom nutes
more then anything) or youre suffering from pH lockout.
The instrument ur taking measurements with and exact numbers would help pinpoint more.
well you are very helpful guys and whith using ph papers i cant be so precise, but i tend to keep the colour of the ph paper between the 6 and 7, i cant do better for now
@paranoidperson what I’m thinking
Have the tips been burned on those lower photos for long? You can tell the first few have been but the couple of pics at the bottom look fresh
Make her a banana tea and she will love ya for it .it has all the potassium and phosphorus and calcium with magnesium
Thats where I was headed @Aussie_autos If those tips were recently burnt, then pH maybe proper, just needs more bloom and mag
@PurpNGold74 has you covered. When you can, get a proper ph meter. you will be a hap hap happy person. I would also cut off your bad leaves, no good anymore 
Your lady will look much better without. You will figure things out with the help of your new community. 
How do you make banana tea?
Awww @Aussie_autos you got me searching now lol. Sounds perfect for a flower brew lol!!
How about banana- eggshell tea?
