Robertsanswered grow question 8 months ago Based on how dark green and Shiney they are,the leaves. I believe the feed amounts are not appropriate. Vegging npk ratio is 3-1-2. Flowering npk ratio is 1-2-3. If feed amount is not right it can cause ph issues in substrate. Which leads to lock out issues. Good run off is also needed to push old salts from fertilizers out as new is entering. With limited information in question, this is what I can speculate.
