Hard to say.. but a pH in of mid 5 is wayyy too low for soil. Get it up around 6.5 This was my issue with FF trio. Tiger bloom is great but it absolutely tanked my pH to problematic levels

Issues after first sledgehammer flush, 4 weeks Hey guys and gals, on week 4 of this indoor, hydro grow and I just hit this plant 5 days ago with fox farms sledgehammer for its first flush. Before this, the plant was growing very well. Is this due to the flush? Should I flush in tap water before next feed? Thx for the help ^^

Leaf curling Major leaf curling on one plant. It has been an issue for 2 weeks now. It's strange, no burnt tips or any other damage in 2 weeks, and it seems to be developing, but almost all of the leaves have a wicked curve at the end. Thinking it's a root issue, but could be a lot of things.

The leaves aren't yellowing yet though which means the plants still feeding from the soil. I've used 'flawless finish' to help also.Any ideas?Is it an issue

New growth and top leaves have some discoloration. Could it be light related, or maybe a zinc deficiency?She has been flowering for about a week now and showing some pale spots. At the start of flower I turned the light up from 200w to 300w. Light is currently at about 20" from the canopy. Plants seem healthy otherwise, should I be concerned?

What are my leaves telling me?Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

Yellow leaves near the harvest This would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest (I tried to water today)

I asked for help before, everyone just tells me what they think is wrong and not the reasons why. If you have an answer it would be appreciated to know your reasoning. Thanks🤘
