What is this deficiency?
Jake13255started grow question 4 years ago
They started off with some brown spots and progressed. Is this phosphorus? I have been feeding with .5-1ml of dyna grow bloom and 2ml of cal mag per gallon watering at about 6.3-4 ph. But i recalibrated my ph pen and did one water since.

Hello mate, to me it seems like you have for sure ph related issues accompanied with nutrient lock. The way your leaves are burnt seems to me like ph fluctuations. I would suggest a good flush with plain phed water and then start feeding. I am not accustomed with gallons but 2ml per gallon seems too low for me. I use advanced nutrients and since week 5 I give her 2 mls per liter. In advanced nutrients apart from the basis which in late flowering I use 3/4 of the recommended dosage per liter all other nutrients are in full strength. Hope was helpful

Ok I’ll be going with increasing the nutes. I did not wanna add too much and hurt the plant because I’ve done it in the past lol. I’ll add about 2ml of the bloom and see how they respond and hold off on cal mag until next watering or the next if they still look good.

Hey mate .. you need more bloom nutes at this stage.. specifically K and P.. the deficiency is more towards K though and would suggest to reduce calmg to alternate feeds...

Yellow leaves (a lot of them)The plant is showing a lot of yellow leaves. I think it's a little bit early to speak about a natural loss by flowering, or not?
There are also a lot of yellowish leaves (more yellow than green even): what is the problem?
the red leaves are normal to this strain I think? Thanks!Week 10

Foglie bruciate.Ciao ragazzi?spero vada tutto bene. Ho delle bruciature nelle foglie di una sola pianta, ho dato bio grow e top max biobizz. Umidità 50 % temperatura 27/30 °c purtroppo. Io penso sia dovuto alle luci troppo vicine, ma volevo un vostro parere. Grazie mille.Week 4
