Leaf problems

and im growing one of these strains in my next grow so hope it comes out well

So should I give then a flush, carry on with veg nuits maybe 🤔 switch to bio bizz grow instead of the fish mix, then adding 0.5ml/l calmag along with bioheaven?

Hi there GTButler, you're seeing a bunch of different symptoms at the same time, the yellowing on the serrated edges of the leafs is from magnesium deficiency, the deformity and burnt tips is from N excess and the downward pointing leaf tips is from root problems/issues related to overwatering. You want to take a look at what you're feeding the plants. Basically you're feeding three additives. What you should be doing is feeding one NPK, one calmag, and one additive. So to fix the magnesium deficiency, add calmag, to fix the N toxicity, you need to get a better NPK ratio for veg , think something like 4-2-2 , and to fix the root zone issue, you should be fine just using the bioheaven you're already using. Hope this helps ! 🚀

If yu using bio biz light mix and only bio buzz nutrients , and going by the schedule than they are not over fertilized. light stress or heat stress or bugs ... with the light mix and Nutes don't worry bout PH it will stay where it needs to stay automatically with biobizz , the reason I use it. Prob light and heat tho

Yea, over fertilization or your light is too close.

I'm using biobizz only using 2ml/l fish mix 2ml bio heaven and 1ml acti-vera an yes ph seems to be about 6.0-6.3

Using biobizz light mix and now in week 5 veg?

Podría ser sobrefertilización. Que fertilizantes utilizas? mides PH ?
